Benefits of technology

The invention describes a way to connect pipes to a casting material using a bush. This allows for a tight connection between the pipe and the casting material, preventing any gaps between them. This also forms a micro-form-locking or integral bond between the bush and the casting material. As a result, the medium (e.g. liquid or gas) that needs to flow through the pipe cannot enter or escape between the casting material and the pipe. This improves the efficiency of the pipe connection and reduces the complexity of the sealing process.

Problems solved by technology

At the pipe connections, the medium to be conducted through the pipe can then undesirably enter such gaps and escape elsewhere.

Embodiment Construction

[0024]Reference will now be made to embodiments of the invention, one or more examples of which are shown in the drawings. Each embodiment is provided by way of explanation of the invention, and not as a limitation of the invention. For example, features illustrated or described as part of one embodiment can be combined with another embodiment to yield still another embodiment. It is intended that the present invention include these and other modifications and variations to the embodiments described herein.

[0025]FIG. 1 shows a section of a pressure die casting 100, which is a transmission housing component. The cast component 100 includes a cast body 110 manufactured with the aid of aluminum die casting, and a steel pipe 120 cored therein, which is designed as a U-bend, by way of example. The steel pipe 120 has, for example, a diameter of eight millimeters (8 mm) to twenty millimeters (20 mm) and a pipe wall thickness of approximately two millimeters (2 mm). Both pipe ends of the st...

Abstract

A metallic cast component (100), which is a housing component, includes a cast body (110) and at least one pipe (120) cored in the cast body (110) and through which a medium (F) is flowable. The pipe (120) includes a pipe connection (121, 122) formed at or in a surface of the cast body (110) on at least one of pipe end of the pipe (120). The pipe (120) also includes, at the pipe end, an enclosing bush (130) embedded in the cast body (110). The enclosing bush (130) effectuating a seal between the pipe end and the cast body (110). A method for manufacturing such a cast component (100) is also provided.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application is related and has right of priority to PCT Application No. PCT / EP2018 / 071962 filed on Aug. 14, 2018 and to German Patent Application No. 10 2017 217 387.4 filed on Sep. 29, 2017, both of which are incorporated by reference in their entirety for all purposes.FIELD OF THE INVENTION[0002]The invention relates generally to a cast component that includes at least one cored pipe, through which a medium can flow. The invention further relates generally to a method for manufacturing this cast component.BACKGROUND[0003]DE 10 2012 223 156 A1 describes a housing (exhaust gas valve housing), which includes at least one heating or cooling duct, which is a pipe enclosed by the housing. The ends of the pipe are designed for the connection of a line. The housing is made of die cast aluminum and the pipe is made of aluminum or copper. In order to manufacture the housing, the preformed pipe is placed, in the manner of a core, into a...
